I just started loading some .223 rem 53 grain v-max bullets. and about one in 3 bullets the polymer tip breaks off when i seat the bullet. Can anyone help me as to how to fix this problem? Ive heard that the seating stem does not fit these bullets. if thats the case will it do the same when i load the 75 grain amax's i want to try next? also how do i fix the seating stem to work?

Also, on a side note, ive had a terrible time getting the primers to fit. seems like 5 out of 25 of the primers i try to load just wont go in the pocket. i assume that primer pocket uniforming will help? ive been using once fired hornady brass and CCI benchrest small rifle primers.

Thanks in advance.
